[jira] Commented: (PIG-1468) DataByteArray.compareTo() does not
compare in lexicographic order
[ https://issues.apache.org/jira/browse/PIG-1468?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12886819#action_12886819 ]
Daniel Dai commented on PIG-1468:
---------------------------------
The other concern is we only change DataByteArray not byte. So comparator for DataType.BYTEARRAY and DataType.BYTE is different. This will cause confusion.

> The compareTo() method of org.apache.pig.data.DataByteArray does not compare items in lexicographic order.
> Actually, it takes into account the signum of the bytes that compose the DataByteArray.
> So, for example, 0xff compares to less than 0x00
